config BATMAN_ADV_BATMAN_V
bool "B.A.T.M.A.N. V protocol"
depends on PACKAGE_kmod-batman-adv
default y
help
This option enables the B.A.T.M.A.N. V protocol, the successor
of the currently used B.A.T.M.A.N. IV protocol. The main
changes include splitting of the OGM protocol into a neighbor
discovery protocol (Echo Location Protocol, ELP) and a new OGM
Protocol OGMv2 for flooding protocol information through the
network, as well as a throughput based metric.
B.A.T.M.A.N. V is currently considered experimental and not
compatible to B.A.T.M.A.N. IV networks.
config BATMAN_ADV_BLA
bool "Bridge Loop Avoidance"
depends on PACKAGE_kmod-batman-adv
select PACKAGE_kmod-lib-crc16
default y
help
This option enables BLA (Bridge Loop Avoidance), a mechanism
to avoid Ethernet frames looping when mesh nodes are connected
to both the same LAN and the same mesh. If you will never use
more than one mesh node in the same LAN, you can safely remove
this feature and save some space.
config BATMAN_ADV_DAT
bool "Distributed ARP Table"
depends on PACKAGE_kmod-batman-adv
default y
help
This option enables DAT (Distributed ARP Table), a DHT based
mechanism that increases ARP reliability on sparse wireless
mesh networks. If you think that your network does not need
this option you can safely remove it and save some space.
config BATMAN_ADV_NC
bool "Network Coding"
depends on PACKAGE_kmod-batman-adv
help
This option enables network coding, a mechanism that aims to
increase the overall network throughput by fusing multiple
packets in one transmission.
Note that interfaces controlled by batman-adv must be manually
configured to have promiscuous mode enabled in order to make
network coding work.
If you think that your network does not need this feature you
can safely disable it and save some space.
config BATMAN_ADV_MCAST
bool "Multicast optimisation"
depends on PACKAGE_kmod-batman-adv
default y
help
This option enables the multicast optimisation which aims to
reduce the air overhead while improving the reliability of
multicast messages.
config BATMAN_ADV_DEBUG
bool "B.A.T.M.A.N. debugging"
depends on PACKAGE_kmod-batman-adv
help
This is an option for use by developers; most people should
say N here. This enables compilation of support for
outputting debugging information to the debugfs log or tracing
buffer. The output is controlled via the batadv netdev specific
log_level setting.
config BATMAN_ADV_TRACING
bool "B.A.T.M.A.N. tracing support"
depends on PACKAGE_kmod-batman-adv
select KERNEL_FTRACE
select KERNEL_ENABLE_DEFAULT_TRACERS
help
This is an option for use by developers; most people should
say N here. Select this option to gather traces like the debug
messages using the generic tracing infrastructure of the kernel.
BATMAN_ADV_DEBUG must also be selected to get trace events for
batadv_dbg.
